🐟 Freshwater Angelfish Care & Facts: Vet Guide 2025 🩺

By Dr Duncan Houston BVSc – Freshwater angelfish (*Pterophyllum scalare*) are elegant, intelligent cichlids native to South America's Amazon Basin. This 2025 vet-reviewed guide explores five key facts—from their history, habitat preferences, and social behavior to care requirements and breeding dynamics—with telehealth support through Ask A Vet for optimal husbandry and health care.

1️⃣ A Storied Origin & Physical Grace

• First documented in 1823 and imported to Europe in the early 1900s, angelfish quickly captivated aquarists with their tall, triangular fins and graceful movement :contentReference[oaicite:3]{index=3}.
• Wild-type *P. scalare* hail from the Amazon, Orinoco, and Guiana Shield river systems, where their vertical stripes provide camouflage among flooded roots and debris :contentReference[oaicite:4]{index=4}.
• Through selective breeding, at least 10 color morphs have emerged—Silver, Zebra, Marble, Koi, Black Lace, Golden, Blushing, Half-Black, Altum, and Leopoldi—each showcasing unique patterns and fin shapes :contentReference[oaicite:5]{index=5}.

2️⃣ Size, Lifespan & Water Preferences

• In captivity, angelfish grow to around 5–6 in (12–15 cm), with fins up to 8–9 in tall in some strains; reaching full size by 6–12 months :contentReference[oaicite:6]{index=6}.
• With proper care, they live 8–12 years; captive-bred specimens often thrive over a decade :contentReference[oaicite:7]{index=7}.
• Ideal water: 76–82 °F (24–28 °C), pH 6.0–7.5, hardness 3–12 dH, ammonia & nitrite at 0 ppm and nitrate <20 ppm :contentReference[oaicite:8]{index=8}.

3️⃣ Behavior & Tank Dynamics

• These semi-aggressive, social fish form monogamous pairs; they may exhibit fin-nipping, especially during breeding or when crowded :contentReference[oaicite:9]{index=9}.
• Angelfish use visual and chemical cues—including “lip locking” or urination—to establish territorial boundaries and breeding bonds :contentReference[oaicite:10]{index=10}.
• Best housed in tall, planted tanks (30–55 gal for a group of 4–6) with driftwood or vertical surfaces for a natural feel :contentReference[oaicite:11]{index=11}.

4️⃣ Omnivorous Diet & Breeding Behavior

• In the wild, they eat small fish fry, insects, worms, crustaceans, and zooplankton; domestically, feed them varied diets: high-quality flakes/pellets + live/frozen brine shrimp, bloodworms, tubifex, daphnia :contentReference[oaicite:12]{index=12}.
• Breeding: Angelfish form pairs, clean flat surfaces (leaves, slate, even tank sides), and lay 100–1,200 eggs. Both parents fan and guard the clutch; fry become free-swimming ~5–7 days post-hatch :contentReference[oaicite:13]{index=13}.

5️⃣ Anfänger-Freundlich with Caveats for Tank Mates

• Their hardiness and grace make them popular—but they need stable water, sufficient space, and adult-friendly tankmates such as larger tetras, gouramis, and Corydoras; avoid small schooling fish that fit easily in their mouths :contentReference[oaicite:14]{index=14}.
• Fast-moving or aggressive species (e.g., tiger barbs) will nip fins; peaceful fauna and plant cover help – angelfish thrive in tall planted environments :contentReference[oaicite:15]{index=15}.

✅ Ask A Vet Telehealth Care Tips 2025

Use the Ask A Vet app throughout the care process for:

• Water test interpretation—including pH, ammonia, nitrite, nitrate stability.
• Behavior and health checks: fin-nipping, territorial signs, abnormal posture, or poor coloration.
• Breeding support: reviewing egg-laying behavior, egg count, fry health, and feeding schedules.
• Illness detection: Ich, fin rot, swim bladder issues—submit macro photos or videos for vet diagnosis.
• Tankmate compatibility: optimizing species combinations and habitat structure.
